Why The Right Blower Flow Rate For Aeration Is Important

As the operator of a wastewater plant, you may already have realized that not all blowers are alike. Therefore, one of the biggest decisions you have to make is which one is the optimal solution for your requirements. Comparing different solutions can be tricky, especially if each blower manufacturer uses its own way to report flow rate and air pressure data.

Before you do anything else, you want to make sure you define the optimal flow rate and air pressure for your aeration process. Getting those requirements right, will ensure you have enough aeration capacity during peak demand hours and a smooth and efficient process during normal operating hours.

When you get the blower air flow rate calculation wrong and undersize your equipment, then your plant will not be able to reach the design treatment capacity. That means you can treat less water or, even worse, you end up with an effluent that does not meet the required standards. Oversizing the blower, on the other hand, will result in a waste of energy because it will either start-stop frequently or run in a blow-off state.
